description
The TM8SK64JPN is a 64M-byte, 144-pin SODIMM. The SODIMM is composed of eight TMS664814DGE,
8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic thin small-outline package (TSOP) mounted on a
substrate with decoupling capacitors. See the TMS664814 data sheet (literature number SMOS695).
operation
The TM8SK64JPN operates as eight TMS664814DGE devices that are connected as shown in the functional
block diagram.
